dose the truck have the big tow package, if yes, take everything, diff, axles, upper and lower arms coil overs. you will be 3in wider in the front, look at Ben's truck it will be that wide with stock wheels.
My self i would also take the spindles and hubs along with the wheels get some spacers for the rear then call PRG for titan uppers and 3in lift coil overs
